### Original putchar with _testbit_ causing Warning 140 and Error 185

Source: https://support.arm.com/documentation/ka003938/1-0

Original serial example from the Getting Started manual that triggers Warning 140 because _testbit_ is undefined (should be _testset_) and Error 185 because the atomic section exceeds 4 instructions.

```c
char putchar (char c)  {                          /*  substitute func for putchar */
  while ((( unsigned char)(tx_in + 1))==tx_out);  /*  buffer full? */
  _atomic_ (0);
  tx_buf [tx_in++] = c;                           /*  put char in buffer */
  _endatomic_ ();
  if (_testbit_ (tx_restart))  {                  /*  if transmits must be restarted */
    S0TIR = 1;                                    /*  enable transmit request */
  }
  return (c);
}

```

### Example µVision Debugger Script File

Source: https://support.arm.com/documentation/ka002991/1-0

Example debugger script file for µVision. Sets watchpoints on myvar and myvar2, defines a signal function that toggles P1 every 5,000 clocks, defines OnResetExec to call EnableTPIU() after reset, changes the program start address to 0x1000, and runs the program stopping at main. All commands from the µVision User's Guide may be used in a script file.

```plaintext
/*-------------------------------------------*/
/* Set Watchpoints                           */
/*-------------------------------------------*/

ws myvar
ws myvar2


/*-------------------------------------------*/
/* Create a Signal Function                  */
/*-------------------------------------------*/

signal void bob(void) {
  while (1) {
    twatch (5000);          /* Delay for 5,000 clocks */
    P1 = ~P1;               /* Toggle P1 Pins */
  }
}

/*-------------------------------------------*/
/* Executes upon software RESET;             */
/*  (Use the function name as is)            */
/*-------------------------------------------*/
FUNC void OnResetExec (void)  {        //
   EnableTPIU();                       // call the initialization function
}

/*-------------------------------------------*/
/* Change the program start address          */
/*-------------------------------------------*/

$=0x1000


/*-------------------------------------------*/
/* Run the Program (stop at main)            */
/*-------------------------------------------*/

g, main
